One of the limitations of using the range is that it is a _____________ measure of variability. It is ______________ susceptible to ______________. It is used mostly with ______________ or ordinal data.
Answer:
One of the limitations of using the range is that it is a simple but poor measure of variability. It is very susceptible to poor representation of data spread. It is used mostly with ordered data or ordinal data.
Step-by-step explanation:
The measure of the range of a set of given data can be established once the difference between the highest and lowest values is known.
The range is simple to use but only considers the smallest and largest data elements in the set without considering the middle values and other values that could influence results if the data spread is to be considered.
Ordinal data aren't numerical data. Examples include Time of day such as morning, noon, night.

Step-by-step explanation:
A line contains the points (-6, -4) and (0, 4). What is the equation of this line in slope-intercept form? A. B. C. y = x – 4 D. y = x + 4
Answer:
y = 4/3 x + 4
Step-by-step explanation:
The general form of the equation of a line is given as
y = mx + c where m is the slope and c is the intercept on the y axis
where the slope m = (y2 - y1)/(x2 - x1)
Hence given the points (-6, -4) and (0, 4)
m = (4 --4) / (0 --6)
= (4+4)/(0+6)
= 8/6
= 4/3
For a line with given points (x1, y1), the equation is given as
y-y1 = m(x-x1)
Hence the equation of this line in slope-intercept form
y - -4 = 4/3(x --6)
y + 4 = 4/3(x + 6)
3y + 12 = 4x + 24
3y = 4x + 24 - 12
3y = 4x + 12
y = 4/3 x + 4
For a line with given points (x2, y2), the equation is given as
y-y2 = m(x-x2)
Hence the equation of this line in slope-intercept form
y-4 = 4/3(x - 0)
multiply through by 3
3y - 12 = 4x
3y = 4x + 12
y = 4/3 x + 4

A

PLEASE HELP!! PERCENTS (:
Answer:
7 is the answer
Explanation:
because if you use a calculator, by doing 10% of 70 which equals to 7 which that is the answer.
Answer:
B: $63
Step-by-step explanation:
You can make an equation: 70(10%)
Which can be simplified into 70(0.1)
70×0.1=7
Since it was discounted, you subtract
$70 - $7 = $63

Step-by-step explanation:
(financial math) Elementary and Secondary Education is paid mostly from:
O Corporate Taxes
О Defense Taxes
O State Taxes
O Federal Taxes
State taxes.
According to Urban dot org, school funding is a blend of federal, state, and local dollars.
State taxes are more likely to be correct due to education being the state's responsibility.
If this is incorrect, please, don't refrain to tell me. Thank you.

Brett has a $30 online gift voucher. He plans to buy as many books as he can. The cost of each book is $4. There is also a single shipping charge of $2. How many books can he afford without spending more than his gift voucher amount?
its an inequality eqution, i already know he can spend 30 or less on the boook
answer:
30 > 4x + 2 and 6 books
step-by-step explanation:
read the question and set up the inequalitylet x = number of books he can afford30 > 4x + 2
30 would be on one side since that's the most he can spend4x because each book is $4+ 2 because there is a charge of $230 > 4x + 2
28 > 4x
7 > x
he can afford 6 booksit cannot be 7 because if he does buy 7 books, it would cost more than $30I need the answer for this. Please help

Explain why one Columm in the hundredths grid is equal to one Columm in a tenths grid.
Answer:
because in each case, the selected column composes one-tenth of the grid in total. The number of blocks is different, but the proportion of space filled is the same.
Step-by-step explanation:
An object is under the influence of a force as represented by the force vs. position graph as
shown in Figure What is the work done as it moves from 0 to 10 m?
Work done = force x distance.
The force is 10N the distance is 10m
Work done = 10 N x 10m = 100 NM = 100 Joules

if a^3-1/a^3=4 then what is the value of a-1/a ??
Answer:
1 or -0.5±1.9365i
Step-by-step explanation:
We know that [tex]x^{3} - y^{3} = (x-y) ^{3} +3xy(x-y)[/tex]
So plug in x=a and y=1/a, (a-1/a)^3+3*a*1/a*(a-1/a)=4
Let a-1/a=k, k^3+3k=4, k=1 or a complex conjugate -0.5±1.9365i
That's the answer.

Complete the steps to identify all potential rational roots of f(x) = 3x2 – x – 4. Values of p are factors of ✔ -4 . Values of q are factors of ✔ 3 Select all of the potential roots. \pm 4/3 \pm 2/3 \pm 3/4 \pm 2 \pm 4 \pm 3/2 I need help with the second one please <3 Thanks
Answer:
-1 and 4/3
Step-by-step explanation:
Given the quadratic equation;
f(x) = 3x^2-x-4
To get all potential roots, we will equate f(x) = 0
3x^2-x-4 = 0
3x^2-4x+3x-4 = 0
x(3x-4)+1(3x-4) = 0
(x+1)(3x-4) = 0
x+1= 0 and 3x-4 = 0
x = -1 and 3x = 4
x = -1 and x= 4/3
Hence the potential roots are -1 and 4/3
Write the number 510 in scientific notation.
Answer:
500+10+0
Step-by-step explanation:
Answer:
5.1 x 102 in scientific notation
Step-by-step explanation:
The purpose of scientific notation is for scientists to write very large, or very small, numbers with ease. Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10bStep 1
step1: To find a, take the number and move a decimal place to the right one position.
Original Number: 510
New Number: 5.10
step 2: Now, to find b, count how many places to the right of the decimal.
New Number: 5 . 1 0
Decimal Count: 1 2
Step 3: Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 5.1 (Please notice any zeroes on the end have been removed)
b = 2
Now the whole thing:
5.1 x 102
Step 4:
Check your work:
102 = 100 x 5.1 = 510

Determine the area of each color
First, we calculate the area of all colors
[tex]Area = \frac{\pi d^2}{4}[/tex]
This gives:
[tex]Area = \frac{22 * 24^2}{7*4}[/tex]
[tex]Area = \frac{12672}{28}[/tex]
[tex]Area = 452.57[/tex]
Since all 4 colors have equal areas, the area of 1 of them is:
[tex]A = \frac{1}{4}Area[/tex]
[tex]A = \frac{1}{4} * 452.57[/tex]
[tex]A = 113.14ft^2[/tex]
[tex]A = 113ft^2[/tex] --- approximated

Solve the following system of equations using substitution.
1)y = 3x - 5
2)5x - 4y = -3
To solve system of equations by substitution, we are going to use the first equation to substitute into the second equation wherever you see y.
[tex]5x - 4y = -3[/tex]
[tex]5x - 4(3x-5) = -3[/tex]
[tex]5x -12x+20=-3[/tex]
[tex]-20[/tex] [tex]-20[/tex]
_______________
[tex]5x-12x=-23[/tex]
[tex]-7x=-23[/tex]
___ ____
[tex]-7[/tex] [tex]-7[/tex]
[tex]x=3.29[/tex] (rounded)
Next, substitute x = 3.29 into the first equation, or to any equation you'd like, to find y.
[tex]y = 3x-5[/tex]
[tex]y = 3(3.29)-5[/tex]
[tex]y = 9.87-5[/tex]
[tex]y = 4.87[/tex]
So, your final answer would be (3.29, 4.87).
